ATTO/mma? fil) effects the withdrawal of the ejector romthe' mold topermit of its adj ustment. These parts and their inode of operation,except in so tar hereinafter indicated, are or may bel sul .ntially likethose disclosel in the application for Letters Patent of E. W'. Pierson, tierial No. 701,013, filed June ll, 1912.

The ejector blades or sections B are directly eugaced and acti'iated bythe bar K, which ri' wes its actuating movement from the ejector slidell', the bar K being slidably mounted at its lower end on the rod Kattached to the vertical slide lf2, which in turn may be raised orlowered by the hand lever le?, in order to connect the bar l with anydesired number ot blades or sections. The bar l( is provided with thepin L, which' normally travels forward and backward in one or another ofthe stationary grooves la', according to the number olf sections il iuoperation, and whereby the jar l held against vertical adjustment, untilthc pin L is shifted into tlieyertical groove M. These parts, and theirmode of operation, are or may be substantially like those disclosed inthe applicationfor Letters Patent of David S. Kennedy, Serial No.787,168, tiled December r?, im.v

As previously stated, it' is the purpose of my invention to securedilercnt and lnovel functions not present in the mechanisms al- .readyreferred to; the first ot' these is the prevention of a change .in thenumber of the ejector sections B, unless the machine lie its normalposition of restlt will be noted that the spring G on the rod lil bearsone end against the arm H', which is formed with a second arm H2 locatedbeyond the pivotal point ll, and which latter arm is normally inengagement with the cam surface il", arranged to rotate in uni son withthe ejector earn D. The cam suriace -l' is formed with a projecting campiece J', so located that when the partsarej in their normal position ofrest, the cam piece contacts with the arm H? and thus holds the arm ll.in its innermost position lwith relation to the spring G. The arm H isbifurcated at its end so as to straddle the rod and is provided with thetransverse pin H1" which lies below and supports the rod, The rod E isformed in its lower side with elongated notch E, which is entered andengaged by the pin lll in the circumstances subsequently to bedescribed.

Fig. 1 illustrates the parts in their nor' mal iposition ot' rest, atwhich time the ejector sections B project into the mold A, the cam piecel engages the arm H so as to hold the arm ll? iirmly in its innermostposition, and the cylindrical or unnotched portion ol' the rod l restsupon the pin 'fl-l1". lnder these conditions the ejector may bewithdrawn from the mold and. its width then varied by including agreater or vimpeded by the pin-H1",` and dunngit-his movement the sprinG heilig compressed Ibetween the collar li and thdarm H1. This operationvwitlulraws"the sections B from the mold A, and shifts they :i1/Katobring the pin L into the grocvell sofas to per;- 1. mit the vertical.moveniciit'lotthei pin in said groove.. Thcpzuts are now free to beIadjusted by thel` manipulation ol the llercrl K3 so as to connect thebar K with any desired numbet` of sections l5, in the manner describedin tire slid Kennedy application. After this operation, the pressureI onthe treadlejll` .is relieved, 'and it returned by the springlr 11 tonormal position, and simultaneouslyltlie expansion o' the compressedspring@F retin-ns the scctionsnB into the mold A, -iu substantially themanner described in the said Yierson application. It will be noted,Ihoueverjtliat in the present instance, and iinlilce the construction othe Pierson a plication, the abutment erin' El* is "held rigidly inposition continuously ivhile the machine occupies its normal position ofrest, whiclrresult arises from the employment of operating means for thearm ll?, which are synchronously related to' the ejecto ctuatiingmechanism. It therefore follows'tliat lall lthe time during this periodthe spring G has a solid abutment, and consequently it tends to resistany accidental displacement of th ejector from the mold. This 'featurepis oimportance' in that it reduces the liability to the dropping out ofthe ejector blades, which sometimes occurs after a completion of themachines cycle, and iarticularly when the mold is adjusted for s ortslugs.v

The foregoing description demonstrates the feasibilityof altering thewidth of the ejector blade when the machinel is in its normal positionoi' rest. lt will now be shown that such alteration is impossible atother times.

Fig@ illustrates the parts immediately after the automatic actuation ofthe machine has been initiated. At this time the cani D has acted uponthe shoe C: and moved the. ejector `lever C and connected partsrearwardly, thereby withdrawing the ejector from the rnold.Simultaneouslythe cam projection J haspassed from under the arm H2, andthe latter moves about its'piyot il until it contacts with thencamsurfaced. The corresponding angular shifting of the connected arm l-llmoves the pin H10 into the notchll" ot the red E, as alsov shown in Fig.Il, thereby locking the rod E against longitudinal morementfby thetreadle l".

lili-z lli rie-iper bar K vertically to connect it with a greater orless number oit ejector sections B; and this condition persists untilthe parts have again-resumed their normal position of rest, asillustrated in Fig. l j

sprevionsly stated, l have shown my 'invention only in preferred formand by way of example, but obviously many alterations and vmoiiiicationsin its construction ancl mode of application will suggest themselves tothose skilled in the art Without departure :from its scope.
